Years after she escaped from an icy torture chamber in an abandoned slaughterhouse, Lucie (Mylène Jampanoï) enlists the help of her closest friend, Anna (Morjana Alaoui), to track down the family who tormented her and exact her revenge. But when Lucie and Anna investigate further, they discover that they've only scratched the surface of an unspeakably vile secret organization. Pascal Laugier directs this ultraviolent horror film.
